Many buildings, whether they are hospitals, educational facilities or office spaces, are decades old and in dire need of significant repair, rejuvenation and reinvention to bring them up to current efficiency, health and safety standards," said Spector Group principal Marc B.
The main drawback to this technique is that there must be a high-enough concentration of metal cations in the water for it to be effective; if the cation concentration is too low -- roughly less than 100 parts per million -- the current efficiency becomes too low and the current acts on more than the heavy metal ions.
